Project description:Response of bronchial epithelial cells to low doses of cigarette smoke condensate and subsequent demethylation agent
| PRJNA114465 | ENA
Project description:The study seeks to identify the epigenetic changes caused by exposure of to cigarette smoke condensate. To this goal human bronchial epithelial cells, BEAS-2B, were treated with 5-aza-2’deoxycitidine and trychostatin A (5AzaC/TSA) subsequent to a chronic exposure (1 month) to cigarette smoke condensate (CSC). As negative control served BEAS-2B cells that were untreated or treated with CSC/DMSO for one month without the subsequent application of 5Aza/TSA. Keywords: stress response

Project description:The study seeks to identify the epigenetic changes caused by exposure of to cigarette smoke condensate. To this goal human bronchial epithelial cells, BEAS-2B, were treated with 5-aza-2âdeoxycitidine and trychostatin A (5AzaC/TSA) subsequent to a chronic exposure (1 month) to cigarette smoke condensate (CSC). As negative control served BEAS-2B cells that were untreated or treated with CSC/DMSO for one month without the subsequent application of 5Aza/TSA. Experiment Overall Design: BEAS-2B Cells were treated for one month with CSC, DMSO, and left untreated. Subsequently half of the samples were treated with the demethylation agent. So that there were six different conditions with three biological replicates each. One sample had to be excluded because of low quality.

Project description:We investigated proteins identified by shotgun proteomics in cytologically normal airway epithelial cells from individuals at different levels of risk for lung cancer. We identified 2869 proteins in bronchial brushings from individuals at low, moderate or high risk for lung cancer. Pathway analysis revealed enrichment of carbohydrate metabolic pathways in high risk individuals. Differential expression of selected proteins was validated by parallel reaction monitoring mass spectrometry in separate individual bronchial brushings. Augmentation of glucose consumption and lactate production measured in human bronchial epithelial cell BEAS2B treated with cigarette smoke condensate and increased synthetic ability and reductive carboxylation revealed by metabolic flux analysis indicated profound metabolic reprogramming.

Project description:Exposure to genotoxic stresses such as cosmic radiation and second-hand tobacco smoke may increase the risk of breast cancer formation. Towards an understanding of how exposure to these genotoxic agents affect breast cancer biogenesis, we have shown that treating non-tumorigenic immortalized breast MCF 10A cells with low doses (0.1 Gray) of radiation as well as cigarette smoke condensate can generate a neoplastic breast cancer phenotype. The transformed phenotype promoted increased mammosphere numbers, altered cell cycle phases, and increased invasion and motility. In addition, exclusion of Hoechst 33342 dye, a surrogate marker for increased ABC transporters, was observed, which indicates a possible increase in drug resistance. Furthermore, differential gene expression profiles were generated from the individual and combination treatment. Overall, the results indicate that when normal breast cells are exposed to low dose radiation in combination with cigarette smoke condensate a phenotype is generated that exhibits traits indicative of neoplastic transformation. Taken together, these results provide a new insight into a possible etiology for breast cancer formation in individuals exposed to cosmic radiation and second-hand smoke. To study the effects of low dose ionizing radiation and tobacco smoke on breast cells, MCF 10A cells were treated either with radiation (Rad - 0.1 Gray) or cigarette smoke condensate (Csc - 10 microgram/ml of medium) or a combination of Rad + Csc). Following treatments, the cells were incubated for 72 hr, RNA extracted and analyzed for differential gene expression pattern.
